Paper Abstract

A single-mode nanoadiabatic tapered optical fiber biosensor was utilized for real-time monitoring of the antimicrobial activity of silver nanoparticles (Ag-NPs) against E. coli. For measuring growth-inhibitory effects, the bacteria were immobilized on the tapered surface. Then, fiber sensor surrounded in glucose growth medium conation different concentration Ag-NP. At the same condition, the growth inhibition of E. coli was measured by colony counting method as a controlling experiment. Interacting Ag-NPs with cells, by anchoring to and penetrating the bacterial cell, the refractive index of the tapered region can be changed that leads to changes in the optical characteristics of the taper.
